Microscopes are equipped with a scale called a reticule . This is built into the eyepiece. The ocular micrometer consists of 50-100 divisions.
Light years
The distances of the Earth are typically measured in kilometers (km) or miles (mi). Alternatively, astronomical units (AU), which is the average distance from the Earth to the Sun, can also be used to measure distances within the solar system.
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
You don't, miles are not a unit in the metric system. All distances are measured in metres. Prefixes are used for multiples or fractions of a metre. Distances that used to be measured in miles would, today, be measured in kilometres.
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
they are measured in AU
The distances are measured from the tip of home plate to the bottom of the fence.
Usually such distances are measured either in light-years, or in parsecs.
Long distances are measured in AU in Eve Online. For short distances, it is measured in KM.
It depends on what you are trying to measure. Long distances usually are measured in miles. Survey distances usually are measured in feet.

distances between cities are usually measured from the central post offices
Usually small distances. You may get rainfall measured in mm.
